Question #: 14922

Question: [Mach3 USB Interface Board] Instructions read 24v on the card, can it support 36vdc ?

Current Solution

The power supply that is used to power this controller must be 24VDC maximum. Any higher voltage and the controller components can be damaged. The 24VDC power supply doesn't need to be a high amp power supply. I would recommend This power supply: https://buildyourcnc.com/item/electronicsAndMotors-power-supply-24v-1a-dc

  • HOW DO I WIRE THE 4TH AXIS THAT YOU SELL. I HAVE MACH3 SOFTWARE. NO INSTRUCTIONS ON YOUR SITE

    The motor that is attached to the 4th axis is wired as follows:

    The motor should have red, green yellow and blue wires coming form the motor. The red and green are paired as one coil and the yellow and blue is paired as the other coil. You can wire the motor to a 3.0 amp driver with red to A+, green to A-, Yellow to B+ and Blue to B-

  • DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?

    The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

  • [575] can the handwheel inputs be used for thc

    I have not tried using the handwheel inputs for anything other than for handwheel operation. I haven't had success using a THC with the Mach3 USB controller. The pokeys57CNC controller is a better solution for THC (torch height controller) and plasma cutter use.

  • Can I power the Mach3 USB interface 24V with a 48V power supply?

    The Mach3 USB interface card uses 5V (powered from the computer's USB) and a 24v to power the inputs, outputs and spindle control

    the mach3 usb interface can be found here:

    https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

    But the mach3 usb does not absolutely need the 24V supply. The 24v supply is only needed if you will be using limit switches (I1-4), VFD controlled automatically and for use with the outputs (O1-4)


    Additional Information:
    The 36v 8.8 amp power supply we typically recommend is for powering the stepper motor drivers.

  • [575] Can this board drive two (2) Y-motors? Design uses 1 X, 2 Y, and 1 Z motor. The schematic has X, Y, Z

    You can use this board to have two motors/drivers on a single axis.

    You have two solutions for this:

    Wire the YP and TD to two drivers so they are receiving the same pulses and direction signals from the controller (if you need the motors to turn in opposite directions, just swap the A and B coils where the motor connects to the driver for one of the drivers/motors). This will free up an axis on the board.

    Use the Mach3 slaave axis option where you resolve the two motors on a single axis by software. This will require you to use the extra axis on the board.

  • [575] can we use two MPG for two axis independant axis movement

    You can use two MGPs (bare MPGs) to provide independent axis control. The handwheel input on this controller contains discrete inputs for the X, Y, Z, and A axes. These inputs can receive a pulse to move their axis. For instance, you can connect an MPG to the X-axis pin and the wheel will move the X-axis only.

    Of course, if you have a traditional pendant, you can move any axis independently from only a single wheel with a switch that selects the axis you wish to move.

  • [575] Is it possible to run board on usb power

    Yes. You don't need to power the board with 24V. The controller will work with only a USB connection to the computer. However, the Input and output terminals (IN1-4 and OUT1-4) will not work without at least 12V on the DCM and 24V terminals.

  • [575] I cannot get the limits to work I’m normally open as you state

    Open the input signals dialog box by clicking on config, then ports and pins, then input signals. For each line item that you use (i.e. x++, y--, etc) make sure the port number is 3.

    Also, make sure there is a 24v power supply connected to the DCM and 24V terminals. One side of the NO on the limit switch must connect to the DCM, or the power supply V- terminal.

  • [575] what would we use for the post processor? for vcarve

  • [575] Hi, Can I use this board with a closed loop stepper?

    Yes, this CNC controller can be used with closed-loop stepper drivers and motors. The loop for control and feedback is between the driver and the motor. The closed-loop driver receives step and direction signals, which this controller will output which furnishes the driver with the necessary signals to move the motor. Additionally, the closed-loop driver can output a fault signal to this controller through the controller's input terminals in case the motor should encounter a situation that prevents the motor from moving so the CNC can shut down.

  • [575] Where can i find a xml file for maxh3turn?

    You can use the mach3turn in the mach3 loader and simply enable the motor outputs. For the inputs and outputs, make sure to use port 3 for the port number and reference the terminal description for the pin number (i.e. IN2 is Pin 2). Don't forget to use the plug RNRMotion.dll in the plugins folder first.

  • [575] I cant get a 5v signal on any of the Outputs on the board. what Port# and Pin #s should I be using on Mach3?

    The Mach3 USB controller does not provide 5V output signals. The Inputs, Outputs, and PWM Spindle Speed terminals are separated from the 5V side of the board. The output terminals use the 24V portion of the controller and you will need a 24V power supply to make these outputs work.

    Please watch the video below to completely understand how the outputs of this controller work. Make sure that you are using the RNRmotion.dll plugin and that the port for each of the outputs is set to port 3.

  • Mach3 USB interface board initial setup. Following instructions in the video "Mach3 USB controller outputs". Arrow keys cause red LED to blink, but cannot duplicate 24V output with M3 (or M4) commands as shown in the video. Do I need to re-install Mach3?

    If the outputs are not functioning as expected on the Mach3 USB controller, confirm that the port for the output is 3. This is a part of the configuration I did not show on the video I created on using the outputs for the RNRMotion controller.

    Additional Information:
    Thanks for your help. Under Ports & Pins>Output Signals I show Output#1 through Output#4 as Enabled. All have Port# set to 3. Pin Numbers for each Output# are same as Output# (Output#1 set to Pin Number 1, etc.).
    Still no voltage showing on output 1 (of the board) when I input M3 in the Input section of the MDI tab. However if (in Spindle Setup tab) I set (in "Relay Control")M3 Output# to 3 and M4 Output# to 4 things work as expected. Is it possible to have the M3 signal show up on Output#1?
    Thanks again.
